Any thoughts why doesnt this code invoke the onResults method ?

-in my AndroidManifest.xml I got the uses-permission I really dont know whats wrong any opinion is welcomed, It seems like the app is somehow skipping initializeSpeechRecognizer();. The app is only supposed to repeat what I said so thats why my processResult method contains only speak("command");
